Apparatus for implementing the systems and methods may include a first fingerprint scanner and a second fingerprint scanner. Each of the first fingerprint scanner and the second fingerprint scanner may capture at least a portion of the user&#39;s biometric information. The apparatus may also include a first display and a second display. The first display may be located proximal to the first fingerprint scanner. The second display may be located proximal to the second fingerprint scanner. Each of the first display and the second display may be configured to display at least one of a plurality of numerical digits. The apparatus may further include a receiver. The receiver may receive information from the first fingerprint scanner, the information relating to user biometric information input into the first fingerprint scanner.

FIELD OF TECHNOLOGY

Aspects of the invention relate to preventing unauthorized capture of a confidential Automated Teller Machine (“ATM”) access sequence.

BACKGROUND

ATMs provide banking customers with the ability to withdraw funds, deposit funds and access bank account information. Because of their highly automated functions, ATMs are generally able to operate without the supervision of a human clerk. As a result, many ATMs are located in a variety of locations remote from banking centers. For example, ATMs may be placed on street corners, at convenience stores, supermarkets or sports arenas. This wide variety of ATM locations provides banking customers with quick access to cash and bank account information in multiple locations.

However, the lack of human supervision at the multiple ATM locations creates the risk of a thief compromising the security of one or more of the ATMs. For example, the thief may place a skimming device over an ATM card slot reader to capture information encrypted in a magnetic stripe of an inserted card. The thief may additionally use a thin keypad overlay affixed to the ATM's keypad to record buttons pressed by a customer. Alternatively, the thief may place a hidden camera on the ATM to record a video of the hand movements of the customer while inputting his PIN. Such information may subsequently be used to gain unauthorized access to the customer's cash and bank account information.

Skimmer devices, keypad overlays and hidden cameras are becoming increasingly common and difficult to detect. A skimmer or keypad overlay may look and feel like a legitimate part of the ATM and may operate in a manner transparent to a customer. A hidden camera the size of a pinhole is sufficient to record PIN information, thus enabling the camera to be easily hidden and hard to identify.

According to the European ATM Security Team (EAST), a not-for-profit payment security organization, ATM crimes in Europe increased 149 percent between 2007 and 2008. Most of the increase has been linked to ATM skimming attacks. During 2008, a total of 10,302 skimming incidents were reported in Europe. In the United States, between April and May of 2010, one bank estimated losses of over 200,000 USD due to compromised PIN numbers.

Therefore, it is desirable to provide systems and methods to reduce the capture and replication of a banking customer's user identification information. Specifically, it is desirable to provide at an ATM a customer authentication method that is difficult to be captured and replicated by an unauthorized user.

SUMMARY OF THE DISCLOSURE

It is an object of this invention to provide systems and methods for authenticating the identity of a user at an ATM. The method may include using a receiver to receive information included on the user's bank card. The method may also include using a first transmitter to transmit a message to a first display and to a second display substantially immediately after receipt of the information included on the user's bank card. The message may instruct each of the first display and the second display to display a numerical digit different from a numerical digit displayed prior to the receipt of the information included on the user's bank card. The method may further include using the receiver to receive information relating to the receipt of first biometric information by a first fingerprint scanner (referred to herein in the alternative, “sensor”) and a first numerical digit displayed by the first display during the receipt of the first biometric information, wherein the first display is located proximal to the first fingerprint scanner.

DETAILED DESCRIPTION OF THE DISCLOSURE

Systems and methods for providing a more secure Automated Teller Machine (“ATM”) transaction are provided. The systems and methods of the invention may increase the difficulty of capturing and replicating a user's identification information at one or more ATMs.

The systems and methods of the invention may include an ATM. In some embodiments, the ATM may include one fingerprint scanner or a plurality of fingerprint scanners. Each of the fingerprint scanner(s) may be configured to capture a digital image of a fingerprint placed on the fingerprint scanner. The ATM may also include one display screen or a plurality of display screens. Each of the fingerprint scanner(s) may be associated with one of the display screen(s). In some embodiments, a fingerprint scanner associated with a display screen may be located proximal to the display screen.

It should be noted that a fingerprint scanner for use in the systems and methods of the invention may use optical fingerprint imaging, ultrasonic sensors, capacitance sensors (passive or active) and/or any other suitable method to capture the digital image of a fingerprint. It should additionally be noted that a display screen for use in the invention may include an LED display, a digital display, a portion of a touch screen and/or any other suitable display.

Each of the display screens may display a number. In some embodiments, each of the numbers 0-9 may be displayed on at least on one of the display screens. The display screens may display the numbers in an order different from an ascending numerical order. The display screens may also display the numbers in a layout different from a conventional numeric layout where the number “1” appears in the top left corner, the number “9” appears in the bottom right corner the number “0” appears in the fourth row, etc. Instead, certain embodiments of the invention include the display screens displaying a randomized numerical layout. For example, a display screen in the top left position may display the number “5” instead the number “1” and a display screen in the bottom right corner may display the number “3” instead of the number “9.” In these embodiments, each of the display screens may display any one of the numbers 0-9 during a randomized display.

In other embodiments, a dynamic display may randomize only a subset of numbers typically located in a single row or single column of a conventional numeric layout. For example, the numbers “1, 2, 3,” which typically appear in the top row of a conventional numeric layout, may be dynamically displayed, in that row, as “3, 1, 2.” Alternatively, the numbers “3, 6, 9,” which typically appear in the last column of a conventional numeric layout, may be dynamically displayed, in that column, as “9, 6, 3.” In these embodiments, each row or column may be randomized individually, retaining the digits conventionally associated with the row or column.

In yet other embodiments, a first subset of display screens may be configured to display two or more numerical digits and a second subset of display screens may be configured to display a single numerical digit. For example, only the top two rows of display screens may display two or more numerical digits. While the bottom rows of display screens may display the numerical digits typically located in a conventional numeric layout. In yet other embodiments, the ATM may include one or more display screens and one or more conventional keys that include a number affixed to the conventional key.

Embodiments of dynamic displays are described in co-pending, commonly-assigned, U.S. patent application Ser. No. 12/983,920, entitled “Dynamic Touch Screen for Automated Teller Machines (“ATMS”),” filed on Jan. 4, 2011, which is hereby incorporated herein by reference in its entirety.

A user may approach an ATM according to the systems and methods of the invention and input user identification information. For example, the user may swipe a user banking card in an ATM card reader, transmit user identification information stored on a mobile phone using near field communications (“NFC”) and/or enter user identification information using any other suitable method.

After inputting the user identification information, the user may be prompted to select his PIN number. In some embodiments, upon input of the user identification information, each of the display screen(s) may display substantially immediately thereafter a numerical digit. The numerical digits displayed may be in a randomized layout different from the conventional numeric layout. In other embodiments, after a user inserts his bank card into the ATM card reader, the display screen(s) may be blank. In these embodiments, touching one of the fingerprint scanners may initiate each of the display screen(s) to display a randomized layout different from the conventional numerical layout. In yet other embodiments, after a user inserts his bank card, two or more of the display screens may display numerical digits different from the numerical digits displayed prior to the user's insertion of his bank card.

The user may select the first number of his PIN by placing a finger on a fingerprint scanner associated with a display screen displaying the first number of his PIN. In some embodiments of the invention, upon receipt of the user biometric information, one or more of the display screens may alter their display. The one or more display screens may alter their display to display a number different from the number displayed prior to the user's selection of the first number of his PIN.

In some embodiments, one or more display screens may alter their display substantially immediately after each input of user biometric information. This may be desirable at least because minimizing the amount of time that a selected number is displayed may increase the difficulty for an observer or machine to observe the number selected. Thus, in some of these embodiments, the input of the last PIN number may generate an additional randomized display or may initiate the display screens to display a blank display in order to reduce the display time of the numerical digits.

In some embodiments of the invention, the numbers displayed by the display screens may remain static at least until the user inputs each of his PIN numbers. In yet other embodiments of the invention, the number of times that one or more display screens alter their display after the receipt of user biometric information may be dynamic. For example, while entering a four digit PIN, two or more of the display screens may alter their display one to four times.

It should be noted that the number of dynamic displays may be randomized, user defined or system defined. It should additionally be noted that a user may be offered the option of opting-out and/or of opting-in to be presented with a dynamic display. In some embodiments, the option to display a conventional layout may be executed any time during an ATM transaction. In some embodiments, the user may be presented with an option to display a conventional layout after at least one failed attempt to enter a correct PIN. In some embodiments, a user may be presented with a message reminding the user that the display is dynamically presented.

It should additionally be noted that a user may be presented with the option of using his biometrics at an ATM before receiving a banking card. In some embodiments, in the event that a user does not desire to use biometrics at an ATM, the banking institution may issue to the user a banking card with a banking card number. The banking card number may include one or more digits, series of digits, or digits that when operated on, produce a sequence of numbers. Any of these digits, series of digits, or sequence of numbers may notify an ATM and/or a central server that the user's ATM identification will not include biometrics. In these embodiments, the ATM may not prompt the user to input biometrics and/or the central server may not require biometric information to validate the user's identity.

In some embodiments, in the event that a user does desire to use biometrics at an ATM, the user's banking card may include a banking card number with one or more digits, series of digits, or digits that when operated on, produce a sequence of numbers. Any of these digits, series of digits, or sequence of numbers may notify an ATM and/or a central server that the user's ATM identification includes biometrics. In these embodiments, the ATM may prompt the user to input biometrics and/or the central server may require biometric information to validate the user's identity.

The user may then select his second PIN number. The user may select his second PIN number by placing a finger on a fingerprint scanner associated with a display screen displaying his second PIN number. The user may repeat this process until he has selected each of his PIN numbers. It should be noted that the invention includes a PIN of any desirable length, such as a four-digit PIN, a six-digit PIN or any other suitable PIN length.

In some embodiments of the invention, the user may place the same finger on each fingerprint scanner while selecting his PIN. In other embodiments, the user may use a sequence of fingers to select his PIN. In some of these embodiments, each finger in the sequence of fingers may be used to select a PIN number. The finger, or sequence of fingers, used by the user to select his PIN may be randomly chosen by the user, user defined or system defined. In some embodiments where the finger or sequence of fingers is system defined, instructions may be displayed on an ATM screen informing the user of which finger to use, or which sequence of fingers to use, while selecting his PIN. It should be noted that, in some embodiments, the user may place two or more fingers on the fingerprint scanner while selecting his PIN.

A fingerprint sequence used by a user to select his PIN may include fingers from a single hand. An exemplary fingerprint sequence may include: 1^(st) finger, 3^(rd) finger, 4^(th) finger, thumb. Alternatively, a fingerprint sequence may combine different fingers from the right (“R”) and left (“L”) hands. An exemplary fingerprint sequence combining different fingers from the right and left hands may include: 1^(st) finger of L hand, 1^(st) finger of R hand, 3^(rd) finger of L hand and 1^(st) finger of L hand. It should be noted that, in some embodiments, a user may input his PIN using the prints of digits of his right and/or left foot. In these embodiments, the ATM may include biometric scanners in locations that accommodate the receipt of the prints of digits of a foot.

Embodiments of fingerprint sequences are described in co-pending, commonly-assigned U.S. patent application Ser. No. 12/983,936, entitled “Utilization of Digit Sequences for Biometric Authentication,” filed on Jan. 4, 2011, which is hereby incorporated herein by reference in its entirety.

A user may be required to select his PIN in sequential order, starting from the first PIN number and ending with the last PIN number. For example, a user with PIN ‘6137’ may enter his PIN by (1) touching a fingerprint scanner associated with the number ‘6,’ (2) touching a fingerprint scanner associated with the number ‘1,’ (3) touching a fingerprint scanner associated with the number ‘3’ and (4) touching a fingerprint scanner associated with the number ‘7.’

In other embodiments, a user may enter the digits of his PIN in any order. For example, in these embodiments, the user with PIN ‘6137’ may enter his PIN by: (1) touching a fingerprint scanner associated with the number ‘1,’ (2) touching a fingerprint scanner associated with the number ‘6,’ (3) touching a fingerprint scanner associated with the number ‘7’ and (4) touching a fingerprint scanner associated with the number ‘3.’

Upon input of user biometric information into a fingerprint scanner, a transmitter may substantially immediately transmit at least a portion of the input biometric information to a receiver. The transmitter may also transmit information relating to the PIN number displayed on the display screen associated with the fingerprint scanner during the receipt of the biometric information. The transmitter may transmit the biometric and PIN number information each time the fingerprint scanner receives user biometric information.

In the event that the ATM determines that information relating to a complete user PIN sequence has been received, the ATM may encrypt at least a portion of the received user identification information, biometric information and PIN numbers. The ATM may subsequently route the encrypted information to a remote location via a telecommunications network. In some embodiments, the remote location may be associated with a third party such as an interbank network, authorization system, or any other suitable platform configured to authorize or assist in the authorization of one or more financial transactions. The third party may be referred to hereinafter as an “ATM server.”

In some embodiments, the ATM may route the encrypted information to the ATM server. Upon receipt of the information, the ATM server may initiate the validation of the biometric information and the PIN numbers. In the event that the biometric information and the PIN numbers are determined to identify a user associated with the user identification information, the ATM server may transmit a message to the ATM, instructing the ATM to initiate a user banking session.

In some embodiments, the ATM server may initiate the validation of the user's identity by decrypting a card number included in the user identification information. The ATM server may subsequently retrieve a PIN offset value, stored in one or more databases, that is associated with the card number. The ATM server may retrieve the PIN offset value by querying the one or more databases.

The ATM server may then send the card number, PIN offset value and input PIN number to a PIN processor. The PIN processor may run a cryptographic function and a key on the card number to get an encrypted number. The key may be a piece of information that determines the functional output of the cryptographic function.

The PIN processor may then take the first four digits of the encrypted number, subtract it from the offset value, and determine if the resultant number matches the input PIN number. A match may indicate that the input PIN is the PIN number associated with the user identification information. The PIN processor may transmit to the ATM server information relating to the validity or invalidity of the input PIN.

After or during the validation of the input PIN, the ATM server may initiate the validation of the biometric information using one or more matching algorithms. The ATM server may validate the biometric information by retrieving user biometric information associated with the card number. The ATM server may retrieve the user biometric information by querying one or more databases.

The retrieved user biometric information may include one or more stored templates. The stored templates may be associated with user identification information, such as a user card number, in the one or more databases. Each of the stored templates may include information relating to at least a portion of a user fingerprint. In exemplary embodiments, the user may input user fingerprint information into a fingerprint scanner located at a banking institution. The input fingerprints may be subsequently stored in the one or more databases. It should be noted that the user may input user fingerprint information in any location suitable to receive user fingerprint information. The input information may be transmitted to the ATM server and subsequently stored in the one or more databases.

A matching algorithm may then be used to compare a stored template against images of one or more fingerprints received from ATM fingerprint scanner(s). It should be noted that, in the embodiments wherein a user may use one or more fingerprints in any desired order to select his PIN, the matching algorithm may compare each of the received fingerprint images against each of the stored templates.

In the embodiments wherein a user uses a fingerprint sequence to input his PIN, each of the images of the fingerprints received may be compared against a single stored template. In these embodiments, the template used for validation of a user fingerprint may be selected based on the order in which the fingerprint was received. For example, a fingerprint that was received after two prior fingerprints may be compared against a template associated with the third fingerprint. In these embodiments, the information transmitted to the ATM server may include an identifier associated with each fingerprint that had been input into a fingerprint scanner. This identifier may inform the matching algorithm of the temporal order in which each fingerprint was received by the ATM (i.e. first, second, third, etc.).

In some embodiments, the matching algorithm may compare a stored template and a received image of a fingerprint by comparing a pattern of ridges and valleys in the stored template with a pattern of ridges and valleys included in the received image. The matching algorithm may execute this comparison by laying one image over another and determining the degree to which they match. In the event that the stored template and received image are similar at or above a threshold level, the matching algorithm may determine that the received fingerprints have properly identified the user associated with the user identification information.

In some embodiments, the matching algorithm may compare the stored template and the received image by comparing certain features of the received image with corresponding features included in the previously stored template. For example, the matching algorithm may compare certain minutiae and/or basic fingerprint patterns included in the stored template with the corresponding minutiae and/or basic fingerprint patterns included in the received image. The minutiae may include one or more of a ridge ending, bifurcation and/or short ridge (or dot). The basic fingerprint patterns may include the arch, whorl and loop. It should be noted that, in these embodiments, the one or more databases may store the type, size and orientation of the aforementioned patterns in addition to the stored template.

In these embodiments, the matching algorithm may graphically compare the received image with the stored template and determine the degree to which they match. In some embodiments, the matching algorithm may be required to find a predetermined number of minutiae patterns that the two prints have in common. In the event that the predetermined number of minutiae patterns are determined to match at, or above, a threshold amount, the matching algorithm may determine that the received fingerprints have properly identified the user associated with the user identification information.

In some embodiments, the ATM server may validate the biometric information by retrieving a stored user fingerprint sequence associated with the card number. The ATM server may retrieve the fingerprint sequence by querying one or more databases.

A matching algorithm may then determine, based on the received biometric information, a fingerprint sequence used by the user while inputting his PIN. For example, the matching algorithm may use the received images of the fingerprints, angles at which the images were received and/or a force resultant on the fingerprint scanner during the input of the biometric information, to determine the user's fingerprint sequence. Upon identification of the user fingerprint sequence, the matching algorithm may compare the identified fingerprint sequence to the stored fingerprint sequence. If the identified and stored fingerprint sequences are the same, the matching algorithm may validate the input fingerprint sequence. It should be noted that these embodiments may or may not include verifying whether or not the input fingerprints are fingerprints associated with the user.

One skilled in the art will appreciate that the aforementioned descriptions of PIN validation and user fingerprint validation are exemplary only. Any suitable method for PIN validation and fingerprint validation may be used to validate the input PIN and fingerprints.

In the event that the ATM server verifies that both the user PIN and the biometric information identify a user associated with the user identification information, the ATM server may authorize the ATM to initiate a user banking session. In the event that the ATM server determines that either the user PIN and/or the biometric information fail to identify the user, the ATM server may instruct the ATM server to deny user access to the ATM.

It should be noted that, in some embodiments, in the event that a central server determines that a user entered an incorrect PIN, the display screens may present another randomized digital display. A user may then be presented with the option of re-entering his PIN. Alternatively, the system may display a conventional layout following a predefined or randomly chosen number of incorrect attempts.

In the event that a user banking session is initiated, the display screens may display a conventional numeric layout. Users may be more comfortable entering non-confidential data using a conventional layout. In other embodiments, the randomized display may remain static and/or change upon the initiation of the user banking session.

It should be noted that the display screens are not limited to displaying single numerical digits. Rather, the display screens may display two or more numerical digits, letters, words, or any other appropriate data.

As will be appreciated by one skilled in the art, although systems and methods of validating a user's identity at an ATM have been illustrated, systems and methods according to the invention may be applicable to other areas and other devices. For example, systems and methods according to the invention may be applied to any apparatus that requires the validation of a user's identity. For example, some embodiments of the invention may be applied to kiosks, pre-paid phone booths or any other suitable electronic device configured to authenticate the identity of a user.

Certain embodiments of the invention may also be implemented on one or more mobile devices. Exemplary mobile devices include mobile phones, personal computers, touch screen telephones, iPads, iPhones, Android phones, tablets, laptops and/or any other suitable electronic device. Exemplary usages of the invention with one or more of the aforementioned mobile devices include a user using a PIN and biometric identification in any method described herein to access to the mobile device itself, to access an application included on the device and/or access secured internet websites and/or to validate his identity to purchase items on the internet.

For example, a mobile device may include one or more fingerprint scanners to receive biometric information. The mobile device may also include numbers, letters and/or phrases selectable via a touch screen and/or mechanical keys. The systems and methods of the invention may then be implemented on the mobile device to verify the identity of the user using the one or more fingerprint scanners and the touch screen/mechanical keys.

Additionally, the systems and methods of the invention may be included in an application configured to be downloaded on a mobile device. In some embodiments, the application may be purchased prior to download. It should be noted that the application may be suitable to be downloaded to an Apple™ mobile device, Android™ mobile device or any other suitable device.

FIG. 9 shows an illustrative method of banking customer 903 utilizing touch screen 905 to select inputs for information entry into an ATM. Inputs displayed may include numeric inputs 909 and/or functional inputs 911. The touch screen 905 may display additional information 912. In FIG. 9, the banking customer 903 may select inputs by touching displayed choices. Touch screen 905 may detect the presence and location of a customer's “touch” within the display area. In FIG. 9 the banking customer 903 is shown selecting an input 907 representing the number zero.

In the systems and methods of the invention, touch screen 905 may display a conventional layout of the numbers 1-9 and/or a randomized display of numbers 1-9. Exemplary randomized layouts that may be displayed by a touch screen such as touch screen 905 are illustrated in FIGS. 17 and 18.

In the event that a user desires to initiate a banking session, the user may enter customer identification information. Subsequently, the user may enter his PIN. In some embodiments, the user may be required to touch fingerprint scanner 914 after each selection of a number included in his PIN number. The user may touch fingerprint scanner 914 using one or more of the fingerprint sequences described herein.

In these embodiments, the ATM may store and transmit information relating to each number selected and the biometric information received after the selection of each of the numbers. The ATM server may subsequently validate the biometric information received and the numbers selected.

It should be noted that, in some embodiments, fingerprint scanner 914 may be integrated into touch screen 905 and/or an ATM that includes touch screen 905. In other embodiments, fingerprint scanner 914 may be physically secured to ATM 914 in a secured location inaccessible to an ATM user and transmit information to and from the ATM using a USB connection.

In some embodiments, fingerprint scanner 914 may be removably coupled to the ATM using a USB port. In these embodiments, a user may input a suitable USB jack into the USB port. The user may then touch the USB-coupled fingerprint sensor with his finger(s) after inputting each of his PIN numbers. The ATM may receive user biometric information through the USB port and subsequently transmit at least a portion of the received information to the ATM server.

It should be noted that the information received via the USB port may be packaged securely prior to entering the ATM. Additionally, the information may be stored in a memory separate from the operational memory of the ATM. The information may then be encrypted and transmitted to the ATM server upon receipt of the user PIN numbers. The information may be transmitted to the ATM without passing through, or being accessible by, the ATM CPU.

It should additionally be noted that the USB port may receive only one or more specific USB jacks. In some embodiments, a user may be required to purchase, or be provided with, a USB compatible with the ATM from one or more banks affiliated with the ATM.

FIG. 10 shows illustrative process 1000. Illustrative process 1000 includes steps that may be performed in some embodiments of the invention. At step 1001 an individual approaches an ATM. At step 1002, the individual enters a PIN on an ATM touch screen using a defined sequence of fingerprints. After entering the PIN and sequence of fingerprints, the information may be transmitted by the ATM to an ATM server.

At step 1003 the ATM server determines whether the correct PIN has been entered. This determination may be executed by the PIN processor. At step, 1004, if the entered PIN is determined to be incorrect, access is denied. At step 1005, if the entered PIN is determined to be correct, the ATM server determines if the correct sequence of fingerprints has been entered. This determination may be executed by the matching algorithm. At step 1006, if the sequence of fingerprints entered does not match a stored template of fingerprints, access is denied. At step 1007, if the sequence of fingerprints entered does match a stored template of fingerprints, access is allowed.

FIG. 11 shows illustrative ATM portion 1100 that may be included in an ATM in accordance with the invention. Illustrative ATM portion 1100 may include display screens 1101, fingerprint scanner(s) with the predetermined formats 1103 and instructions 1102. Although display screens 1101 display a conventional numeric layout, it should be noted that display screens 1101 may be configured to display any randomized layout of numbers included in the systems and methods of the invention.

Instructions 1102 may include a sequence of fingerprints to be used by a user while selecting his PIN. In some of these embodiments, information relating to the sequence of fingerprints may be transmitted to the ATM server upon receipt of an ATM PIN. The matching algorithm may then use the information relating to the sequence of fingerprints to select the stored template(s) to be used in verifying input biometric information.

Although instructions 1102 are displayed on the ATM in FIG. 11, in other embodiments of the invention instructions 1102 may be electronically transmitted to an ATM user by e-mail, text, or displayed on a user banking page. In these embodiments, instructions 1102 may not be displayed on an ATM. Rather, the user may be required to remember his fingerprint sequence or store his sequence in a location accessible to him prior to initiating a banking transaction. In other embodiments, the sequence of fingerprints may be transmitted to the user by e-mail or text after input of his banking card or other user identification information into the ATM.

FIG. 12 shows an illustrative sequence of fingerprints used by a user to select his PIN in accordance with the systems and methods of the invention. In FIG. 12, a user with PIN ‘5283’ is inputting his PIN by touching fingerprint scanners 1206 using a fingerprint sequence. It should be noted that, in FIG. 12, the user is inputting his PIN using the fingerprint sequence defined in instructions 1102 included in FIG. 11. Specifically, the user is using the fingerprint sequence of index finger of left hand 1202, middle finger of left hand 1203, left thumb 1204 and index finger of right hand 1205 to select his displayed PIN numbers.

FIG. 13 shows an illustrative sequence of prints of digits of the foot used by a user to select his PIN in accordance with the systems and methods of the invention. In FIG. 13, a user with PIN ‘5283’ is inputting his PIN by touching scanners 1306 using a sequence of prints of digits of the foot. Specifically, the user is using the sequence of index digit of left foot 1302, middle digit of left foot 1303, right-most toe of left foot 1304 and index digit of right foot 1305 to select his displayed PIN numbers. It should be noted that scanners 1306 that are receiving the biometric information may be located at the ATM in a location that accommodates the input of the prints of digits of one or more feet.

FIG. 14 shows illustrative process 1400. Illustrative process 1400 includes steps that may be performed by the ATM, the ATM server, the PIN processor and/or the matching algorithm, either alone or in combination with one or more of the other listed devices, in accordance with the systems and methods of the invention.

At step 1402, a user or banking customer may insert a bank card into an ATM. Following insertion of the bank card, at step 1403 the ATM may display to the user a dynamic display of inputs for the user to use while entering his PIN. For example, the dynamic display may be a randomized display of the numbers 1-9 or a non-conventional pattern of presentation of the numbers 1-9.

At step 1404, the user may be presented with an option to opt-out of the dynamic display. If the user executes a selection indicating his desire to opt-out of the dynamic display, at step 1405 the display screens may display a conventional layout. If the user does not execute a selection to opt-out of the dynamic display, the user may select his PIN from the dynamic display using a sequence of fingerprints at step 1406.

At step 1407, a PIN processor may determine if a correct PIN has been entered. In the event that the PIN processor determines that an incorrect PIN has been entered, the ATM or PIN processor may determine at step 1408 if a threshold number of incorrect PIN entries has been attempted. If the PIN processor or ATM determines that the threshold number of incorrect PIN entries has not been met and/or exceeded, the user may again be presented with a randomized selection of inputs at step 1406. If the PIN processor or ATM determines that the threshold number of incorrect PIN entries has been met and/or exceeded, the ATM may deny access to the user at step 1410.

In the event that the PIN processor determines that a correct PIN has been entered, a matching algorithm may determine at step 1409 if a correct sequence of fingerprints has been entered. If the matching algorithm determines that the correct sequence of fingerprints has not been entered, ATM access may be denied to the user at step 1410. If the matching algorithm determines that the correct sequence of fingerprints has been entered, the ATM may allow user access to banking account information at step 1411. In some embodiments, after the granting of access, the display screens may display a conventional layout at step 1412.

FIG. 15 shows illustrative ATM portion 1501. Illustrative ATM portion 1501 may be included on an ATM in accordance with the systems and methods of the invention. Illustrative ATM portion 1501 includes key(s) 1503 and fingerprint scanner(s) 1505. A user inputting his PIN using illustrative ATM portion 1501 may select each of his PIN numbers by touching the fingerprint scanners associated with his PIN numbers. The user may also depress the key associated with his PIN numbers during the input of the biometric information.

FIG. 16 shows illustrative ATM portion 1601. Illustrative ATM portion 1601 may be included on an ATM in accordance with the systems and methods of the invention. Illustrative ATM portion 1601 includes multiple depressible keys.

A user inputting his PIN using illustrative ATM portion 1601 may select one of his PIN numbers by depressing the key that displays his PIN number. After the depression of the appropriate key, the user may subsequently touch one of fingerprint scanners 1611. The user may use this pattern of (1) selecting a PIN number and (2) subsequently touching a fingerprint scanner while inputting of each of his PIN numbers. In these embodiments, a receiver may electronically associate each fingerprint input into the scanner with a PIN number selected prior to the receipt of the input fingerprint. The matching algorithm may use this information to determine the appropriate template to use when validating the input fingerprint(s).

In some embodiments, the user may touch any one of scanners 1611 after the depression of a key. In these embodiments, one or more of scanners 1611 may be included in illustrative ATM portion 1601.

In other embodiments, after depressing a key, the user may be required to touch a fingerprint scanner located in the same row as the row in which he depressed the key. For example, a user selecting the key 1609 may be required to subsequently touch fingerprint scanner 1611 located in the same row as key 1606. In some of these embodiments, each of fingerprint scanners 1611 may be included in illustrative ATM portion 1601.

In FIG. 16, the positions of functional inputs, in addition to the positions of numeric inputs, are randomized. Specifically, enter function 1603 is displayed in a position that conventionally displays the number one, as opposed being displayed among functional inputs 1605. Additionally, stop function 1607 is displayed in a position that conventionally displays the number five.

It should be noted that, in some embodiments of the invention, all keys presented for user selection, including functional keys, may be dynamically displayed by the display screens.

FIG. 17 shows another dynamic display of an illustrative non-conventional pattern of presentation of inputs available for a user to select. The dynamic display may be displayed on an ATM touch screen.

FIG. 17 shows the numeric inputs displayed in an oval shape 1701. Although the sequential order of the numbers displayed has not been changed, the pattern of the presentation alters the appearance of the presented inputs from a conventional layout. Each customer may be presented with a pattern randomly chosen from a set of defined patterns (not shown). Varying the different patterns presented preferably makes more difficult, for a thief, mapping hand movements to inputs selected.

In some embodiments, the shape or pattern formed by a display of the inputs may be dynamically altered. For example, instead of displaying inputs in a conventional rectangular shape, inputs may be dynamically displayed in a diamond or oval shape.

In some embodiments, the inputs that form a particular shape may be presented in sequential order. For example, if numerical inputs are displayed in an oval shape, the number “1” may be displayed on the top of the oval followed by the number “2” and then the numbers “3,” “4,” “6,” “7,” “8,” “9,” and “0”. The number “0” would close the oval, and be followed by the number “1.” In some embodiments, both the order of the inputs and the pattern of the inputs may be dynamically displayed.

For touch screen ATMs, the position of the displayed keys may be shifted to any position within the display area of the ATM screen. Shifting the position of displayed keys with respect to the overall display may allow a user to enter a PIN outside the view of a human observer or hidden camera.

In some embodiments, the touch screen of an ATM may offer a narrow viewing angle. A narrow viewing angle reduces the possibility that a camera or observer may view the specific input represented by a particular key.

The display illustrated in FIG. 17 may include fingerprint scanner 1703. In some embodiments, after each selection of a user PIN number displayed on the touch screen, the user may be required to touch the fingerprint scanner. The user may use this pattern of (1) selecting a PIN number and (2) subsequently touching a fingerprint scanner, while inputting of each of his PIN numbers. In these embodiments, a receiver may electronically associate each fingerprint input into the scanner with a PIN number selected prior to the receipt of the input fingerprint. The matching algorithm may use this information to determine the appropriate template to use when validating the input fingerprint(s).

FIG. 18 shows dynamic display 1801 based on shifting off-center, with respect to the overall display, the position of the displayed inputs. In FIG. 18 the numeric inputs 1805 and functional inputs 1807 have been shifted toward the top of display 1801. Additional information 1803 has been shifted toward the bottom of display 1801. Varying the positions of displayed inputs relative to the center of display 1801 preferably makes it more difficult for a hidden camera to record the hand movements of a customer.

The display illustrated in FIG. 18 may include fingerprint scanner 1809. In some embodiments, after each selection of a user PIN number displayed on the touch screen, the user may be required to touch the fingerprint scanner. The user may use this pattern of (1) selecting a PIN number and (2) subsequently touching a fingerprint scanner, while inputting of each of his PIN numbers. In these embodiments, a receiver may electronically associate each fingerprint input into the scanner with a PIN number selected prior to the receipt of the input fingerprint. The matching algorithm may use this information to determine the appropriate template to use when validating the input fingerprint(s).

Alternatively, the user may use a pattern of (1) touching a fingerprint scanner and (2) selecting a PIN number, while inputting each of his PIN numbers. In these embodiments, a receiver may electronically associate each fingerprint input into the scanner with a PIN number selected prior to the receipt of the input fingerprint. The matching algorithm may use this information to determine the appropriate template to use when validating the input fingerprint(s).

It should be noted that the patterns of touching the fingerprint scanner(s) and selecting PIN numbers may be included in multiple embodiments of the invention. For example, the patterns may be used on an ATM, a mobile phone, a personal computer, a tablet, or any other electronic device that includes mechanical keys/a touch screen and one or more fingerprint scanners.

It should additionally be noted that the layout of the PIN numbers may or may not change after one or more selections executed by the user when selecting his PIN number(s).

In yet other embodiments, a user may input a single piece of biometric information into fingerprint scanner 1809. In some of these embodiments, the user may continue to input the single piece of biometric information while selecting each of his PIN numbers. For example, a user may place a designated finger on fingerprint scanner 1809 and select his PIN numbers while his designated finger remains on fingerprint scanner 1809. It should be noted that the display of the PIN numbers may be static or may vary at least once while the user selects his PIN numbers.

FIG. 19 shows illustrative ATM portion 1900 that may be included in an ATM in accordance with the invention. Illustrative ATM portion 1900 may include display screen(s) 1901, fingerprint scanner(s) 1903 and instructions 1902. In FIG. 19, display screens 1901 display a randomized layout of the numbers 0-9.

Instructions 1902 include a statement of a sequence of fingerprints to be used by a user while selecting his PIN numbers. It should be noted that, although instructions 1902 are displayed on the ATM in FIG. 19, in other embodiments of the invention instructions 1902 may be electronically transmitted to an ATM user by e-mail, text, or displayed on a user banking page. In these embodiments, instructions 1902 may not be displayed on an ATM. Rather, the user may be required to remember his fingerprint sequence or store his sequence in a location accessible to him prior to initiating a banking transaction. In other embodiments, the sequence of fingerprints may be transmitted to the user by e-mail or text after input of his banking card or other user identification information into the ATM.
